How to lay the floor for underfloor heating
As winter approaches, floor heating has become the preferred heating method for many families. However, laying the floor for underfloor heating is a science, and improper selection may affect the heating effect or even damage the floor. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the laying method of floor heating floors.
1. Selection of floor heating floor materials

Floor heating floors need to have good thermal conductivity, stability and environmental protection. The following is a comparison of recently popular floor heating floor materials:
| Material type | thermal conductivity | Stability | Environmental protection | Price range (yuan/㎡) |
|---|---|---|---|---|
| Solid wood composite flooring | good | high | Excellent | 200-500 |
| laminate flooring | Excellent | higher | good | 100-300 |
| SPC stone plastic floor | Excellent | extremely high | Excellent | 150-400 |
| tiles | Excellent | extremely high | Excellent | 80-500 |
2. Steps for laying floor heating floors
1.Ground leveling: Before laying floor heating, ensure that the ground is flat and the height difference does not exceed 3mm. Recent hot searches show that many users ignore this step, resulting in hollow floors.
2.Laying moisture-proof membrane: Choose a moisture-proof film with moderate thickness (recommended 0.2mm-0.5mm) to prevent moisture from affecting the floor. Note that the seams of the moisture-proof membrane need to overlap by more than 5cm.
3.floor installation: Suspended laying method is adopted, and 8-12mm expansion joints are reserved on the floor and wall. The "lock-type floor" that has been hotly discussed in decoration forums recently is more suitable for floor heating environments.
4.temperature control: When using floor heating for the first time after laying, it needs to be heated step by step. The daily temperature rise should not exceed 5℃, and the final temperature is recommended not to exceed 28℃.
3. Answers to recent hot questions
Based on the search data of the past 10 days, the following high-frequency questions have been sorted out:
| question | solution | Related search volume (times/day) |
|---|---|---|
| What should I do if the underfloor heating floor bulges? | Stop heating immediately and contact a professional to check the humidity | 1,200+ |
| Which flooring is the most energy efficient? | SPC stone plastic floor has the highest thermal conductivity (0.35W/m·K) | 850+ |
| Does the underfloor heating floor have a peculiar smell? | Choose E0 grade environmentally friendly materials and ventilate them for 7 days after installation | 680+ |
4. Expert advice
1. According to the latest data from the China Forest Products Industry Association, the moisture content of the floor in a floor heating environment should be controlled between 8% and 12%.
2. The recent hot topic on Douyin # Floor Heating Pit Avoidance Guide emphasizes: Avoid using floors with a thickness exceeding 15mm, otherwise it will affect the thermal efficiency by more than 30%.
3. Zhihu Hot Post Suggestion: Perform floor maintenance once a year before and after the heating season, and use a special floor heating floor maintenance agent.
5. Future trends
Judging from recent industry exhibition information, a number of new floor heating-specific floors will be launched in 2024:
| Product name | Innovation point | Estimated time to market |
|---|---|---|
| Graphene composite floor | Thermal conductivity efficiency increased by 40% | 2024Q1 |
| Intelligent temperature control floor | Built-in temperature sensor | 2024Q2 |
Summary: The laying of floor heating floors requires comprehensive consideration of material characteristics, construction technology and subsequent maintenance. Choosing the right products and following correct installation methods will ensure a comfortable and energy-saving heating experience. It is recommended that consumers refer to the latest industry standards (GB/T 35913-2018) when purchasing, and pay attention to real-time evaluation data released by authoritative platforms.
